"I got what you asked for, Zecora. I hope it's enough!"

Fluttershy hands over a bag of chicken feathers to her zebra friend, Zecora.

"Ah, thank you, dear Fluttershy. I needed these, I will not lie! By the way, how was your journey here? Was it pleasant or filled with fear?" rhymes the odd, but wise zebra.

"The Everfree Forest can be a bit… scary, at times, but I’m always happy to visit your hut, Zeroca. After all, you did help me with my problem. It’s the least I can do", said Fluttershy says reassuringly.

“That is quite a load of my mind. I’d hate for you to be in a bind.”

“Um… yeah. So, uh, are those feathers for a new potion you are brewing up?”

"Oh ho! Not so! My pillow has been looking flat, so extra feathers would fix that."

Fluttershy is slightly disappointed that she is unable to see Zecora in action. The skilled alchemist is able to create amazing magics without the use of a unicorn horn, something that she has never seen before until their first meeting.

"However, you have been a dear friend to me. If magic is what you want to see, say the word and I'll make a brew: A helpful present from me to you!"

Fluttershy's wings spring up in excitement! A gift from Zecora is a special treat, indeed. It's like getting a wish from a genie!

“Oh, no. I couldn’t ask you to do something like that for me. You’ve already done enough” says Fluttershy, overreaching to act as modest as possible.

“Hahaha, so you say, but there’s more that your wings convey”, Zecora points out.

“Hehe, I guess they do. Sorry, um, if it's not too much trouble, I do have something in mind..."

"If I can help, then don't be meek. What is your wish? Speak, friend. Speak!"

“Well, um, you know how you made that last potion for me?

Zecora nods her head.

“Well, I’ve been thinking about myself, and I’m very worried that if I told anypony I knew about my… “interests”, ponies might find me to be, um… a freak.” Fluttershy whispers the last two words of her sentence. Zecora lowers her head in contemplative thought.

“Have you ever thought to tell your friends your fears? I’m sure that they would lend you their ears.”

“OH! No, I couldn’t! They’re the best things about my life. I don’t want to do something stupid like tell them that I have a kink for insect stings. They would think I’m gross and never want to see me again.”

Fluttershy shuts her eyes and pictures the scenario in her head. Everypony hates to be stung, so why does she like it? The fear that the other ponies have of them could potentially ostracize her from the society if she told anypony, and they would label her to forever be an outcast. Who’s to say her friends wouldn’t do the same?

Zecora places her hoof on Fluttershy’s chin and lifts it gently; making her eyes met Zecora’s when they eventually open.

“Everypony has guilty pleasures, too. Why should they have any right to chastise you?” says Zecora.

“Well… Maybe it’s because mine is so weird”, whispers Fluttershy, meekly.

“It’s obscure, there’s no doubt. But there’s nothing for you to worry about. Ponies are like clocks, understand? Some are small and some are grand, but many have a different design. Though they all tell time when the gears all click, they are built in different ways that makes them tick. You’re no different, Fluttershy. Though you think you might be sick or are part of a divine trick, I assure you that what you like is what makes you tick. So, for my sake, don’t think you’re bizarre. Do not feel ashamed about who you are. If you tell your friends your concerns, then you will see that they will still love you.”

“You really mean that?”

“I guarantee.”

Fluttershy, with tears in her eyes, wraps her hooves around Zecora. She needed to hear this for a very long time.

“Now, Fluttershy, an idea has risen. I know what might help your friends how to listen”, says Zecora.

“You do?”

“I’ll concoct a potion to reverse pain to pleasure. Use this as your diplomatic measure. They’ll learn what makes you tick like I do, and I know they’ll come to better understand you.”

“Thank you, Zecora!”

___________________________________________________________________________________________________________________________________________________

Fluttershy approaches the doorsteps of Twilight Sparkle’s crystal castle with Zecora’s potion in her saddle bag. Her knees are shaking, as she isn’t sure if this is going to work, but she was willing to give it a try anyway.

“Have courage, Fluttershy”, she says to herself as she raps on the front door.

Twilight opens the door to find her friend smiling nervously.

“Oh, Hi, Fluttershy”, the purple unicorn greets.

“Hey, Twilight”, Fluttershy tries to say as loud as she can, which is normal volume for everyone else.

“I didn’t know you were visiting.”

“Well, I… kinda wanted to talk to you. Have you had any luck replacing all your notes since...Well, you know."

"Oh, well, it's going to be a long time to get everything written down again, but I'm confident that I'll have everything back in order."

“O-Oh, well, good. Um, can I suggest that you and I perform a field study?”

Twilight lights up at the sound of research being made.

“Sure! What’s it about?”

“Um… It’s about… various forms of insects…”

“Interesting. What kind?”

“Oh, you know, bees, wasps, that kind of thing.”

“Oh.” Twilight starts to sweat a bit. “Um, I don’t know. They’ve already been documented in many books before.”

“R-right. But, I’ve always wondered, what kind of insect stings hurt the most between… all of… them.”

Twilight give Fluttershy a weird look. “Um, why would you want to document something like that?”

“Well, it’s because… Can I come inside for a second?”

“Sure.”

Twilight lets Fluttershy into the main foyer in her castle and closes the door.

“Now, then. Why do you need to know what stings hurt the most?”

“It’s because…”

Fluttershy sweats profusely.

“I get… sexually aroused by insect stings.”

“Oh…Wait, wha-“

Fluttershy throws herself in front of Twilight, with her hooves grabbing on to Twilight’s.

“I’m sorry! Please! Please don’t hate me! I know I’m weird but Zecora said you would understand and-“

“Zecora knows about this, too?” Twilight interrupts.

“Yes. She gave me a potion that made me immune to venom, but I didn’t want to tell you girls because you would think I’m a freak!” Fluttershy starts to bawl. Despite the confidence and the assurity that she gained from Zecora, she still buckles under the pressure of being judged by her friend. However, Twilight starts to chuckle to herself.

“Are you… are you laughing at me?” asked Fluttershy.

“Hehe, no, Fluttershy. It’s ok. I don’t mind that you like that kind of stuff. Did you know the technical term for your type of fetish is called melissophillia?”

“There’s a term for that? Y-You aren’t disgusted with me?”

“I’m surprised, I know that much. One doesn’t just knock on the door and says something like that. But, I understand how you feel.”
A huge relief coursed through Fluttershy. “Thank you, Twilight…”

“Anytime, Fluttershy.”

“So, do you want to do that field study?”

“Oooh, um, I know you keep a lot of different bugs where you live. But the idea of getting hurt isn’t appealing to me.”

“That’s why I had Zecora make me this.” Fluttershy takes out a flask of the potion.

“What is that?” asked Twilight curiously.

“It’s a potion that turns pain into pleasure. She said anypony who would drink it would know how I feel. Please, Twilight, drink it and do this with me.”

This is an odd series of events for Twilight. She had a lot of doubts, but Fluttershy had put her friendship on the line with Twilight and showed so much confidence by putting her trust in her. The best that she can do is return the favor.

"Well, I don't think anypony has made a study like this before. I'd love to try and document what kind of results we can get" she agreed.

"R-really?!"

"Yeah, I've already been stung by a lot of bees in my lifetime. What's a few more? That and... It's really brave of you to pour your heart out like that. If this strengthens our friendship, I’ll do it."

"Oh, Twilight! Thank you for giving this a chance!"

"N-No problem, Fluttershy."

___________________________________________________________________________________________________________________________________________________

Back at Fluttershy's cottage, she and Twilight prepare for the experiments. Fluttershy gathers a wide variety of stinging insects and first aid, just in case anything goes wrong. Twilight prepares a writing area for her to make notes outside during the stinging process.

"Ok, Fluttershy. How are we going to do this?" Twilight queries.

"Well, first, you need to drink the potion that Zecora gave us. Second, I'll choose the weakest looking insects to sting you and work our way up. Finally, after each sting, you write down how it feels in a scale of one to five", Fluttershy answers.

"Where exactly are they stinging me?"

"I find the... butt to be the best place."

"The... butt?"

"Right. You would need to bend over and lift your tail high so you don't obstruct them from making contact."

"Exactly how many times have you done this?"

"Too many to count."

"Well... Ok. I trust you."

Twilight pops the cork of the potion bottle and begins to drink. It's very fruity and burns the throat as it goes down like wine. Unlike wine, however, the burning sensation turns into a very euphoric feeling.

"W-wow!" she shouts.

"How is it?" asks Fluttershy.

"I feel pretty relaxed... Ok. Let's do this."

Twilight sets her notepad and pen on the ground in of her, and then she puts her head down and her hindquarters up. A flick of the tail reveals her sex for all to see. Her buttocks were a mix between toned and plump. She's done a lot of running, but a lot of sitting, too. Fluttershy couldn't help staring at her marehood, but also her purple star above it. Although she started this exercise as friends, she couldn’t help but feel aroused, wondering what it would be like to sting her best friend on her soft flanks.

"Fluttershy, are we ready to get started?"

"Huh? Oh, oh yeah. First up, the sweat bee."

The sweat bee flies towards Twilight's butt and hovers over it, waiting for the go-ahead.

"Ready?"

"Y-yeah."

"Go for it!"

The sweat bee dives makes contact with Twilight's rump, fighting through the fur to reach the skin. Upon its discovery, it stings her rump as hard as it possibly could.

"Oh!"

Satisfied, the sweat bee dislodges its stinger and flies back to the line-up.

"How was it?"

"It was like... somepony pulled a single strand of hair from my butt."

"And?"

"Giving it a 1 out of 5 is being generous..."

The sweat bee looks very disappointed...

"Awww, don't feel bad. You did what you could. After all, I always appreciate your efforts!"

The sweat bee perked up from Fluttershy’s kind words. Next up is the fire ant. Fluttershy placed the little guy on her hoof and onto Twilight's left cheek.

"Let's see if you live up to your name", Twilight said coyly.

Taking this as a challenge, the fire ant clamps on to Twilight's rear with its jaws and raises its abdomen. With a hearty thrust, it shoves its stinger into her backside. The venom gets to work in making a burning sensation.

"Ow."

Suddenly, the burning feeling starts to soothe into something odd. It's like the feeling of a hoof gently caressing her butt, nursing her wound.

"Uh, Fluttershy, I think that Zecora's potion is working..."

"And? How'd he do?"

"2 out of 5, it hurt, but it wasn't bad...Not bad at all."

After, setting the ant back down to the ground, next up is Fluttershy's favorite, the yellow jacket.

"So the potion works well?" asks Fluttershy.

"Mm-hm. It felt nice afterward", assures Twilight

"Well, this should make it a bit more interesting. Attack, little one."

By Fluttershy’s command, the wasp flies high, making a small loop, before divebombing Twilight’s right cheek. The stinger pierces deep, emptying its sac of venom into her skin.

"Ow!"

But, as the pain was about to take hold, Twilight’s legs started to quiver. Her backside tickled, making a feeling like somepony was rubbing her sensually.

"W-what is going on?" Twilight asks, moaning a bit.

"Are you all right?"

"2.5.... 2.5 out of 5..."

"Ok, I'll call in the next insect."

"I can't wait," Twilight mutters in her breath.

Fluttershy calls up to bat the insect that is infamous in its sting the world over.

"Honey bees should be old hat to you, Twilight."

"Yeah... Let him lay into me."

"Excuse me?"

Twilight said nothing else. She put her head to the grass, wondering what has gotten over her.

"Well, go on ahead, little one", commanded Fluttershy.

The bee lives up to its name by making a beeline to her exposed ass. One more stinger penetrates her soft supple buttocks as the venom, more potent than the yellow jacket's, begin to spread throughout her cheek.

"Ah!"

The potion takes hold once more. This time, the area of effect makes the pleasure that much greater. Something starts to take hold of urges. Fluttershy spots Twilight's pussy starting to wink and moisten. Truthfully, Fluttershy could hardly contain herself, either.

"How was it?" Fluttershy asks again.

"A...A three. It felt so painful, but then it felt so..."

"Good."

"Yes! Is... is this how you feel?"

"Exactly. I can't control myself. I get the same rushes you do. Zecora's potion makes you feel what I feel."

Fluttershy licks her lips. “Should I kiss it to make it feel better?”

Before Twilight could answer, Fluttershy plants her lips upon the sting wound with a moan escaping from Twilight’s lips.

"Give me another!"

"As you wish."

Twilight looks behind her to see the biggest paper wasp she has ever seen. It terrified her but, at the same time, it made her wet with anticipation.

"Give it to her good" Fluttershy said with a smirk.

The wasp wastes no time in delivering another powerful blow to Twilight's behind. The massive shock of his stinger makes Twilight convulse in pain.

"Ahh, AH!"

The agony flows through her, making her heart pulse and adrenaline flow. The pleasure balances out, sending tingling sensations inside her vaginal area. Instinctively, her hoof reaches out to satiate her primal urges.

"This... This is incredible. I can't help myself..."

"Once you get a taste of venom, there is no going back. The sting is so much sweeter when sexual pleasures are its driving force."

Fluttershy reaches to move Twilight’s hoof away from her marehood.

"Now, let me have a taste of the honey my little ones have produced.

Fluttershy traces her tongue around Twilight's moist vulva, sampling a flavor of her pain-induced love juices.

"Sweet Celestia, this feels so goooood."

Twilight forgot about the sting rating, and even the experiment altogether, as Fluttershy continues to stroke her tongue up and down the path between Twilight’s lovely lips. Then, Fluttershy began to suck on Twilight’s clitoris and Twilight moans in absolute ecstasy. Feeling that the sensation of the previous sting was starting to lose its edge, Fluttershy summons the new insect to the targeting range.

"Now we are getting to the good stuff", Fluttershy says playfully. A Tarantula Hawk swoops in front of Twilight's face, surprising her with its loud buzzing.

"Show her what you are going to do..."

The hornet extends its stinger to the length of a pencil’s tip. Twilight's heartbeat quickens as she gets an eyeful of what she is in for.

"That's right, Twilight. That long and scary stinger is going right inside your butt. Do you feel the fear? The thrill? The anticipation? I feel it, too."

Twilight couldn't believe it. Fluttershy has changed into a completely different pony. But even then, Twilight couldn’t help but give her backside a sultry shake, urging the wasp to attack it.

"Look at her. She’s practically begging to be at the receiving end of your venomous blade. I think you should grant her wish." Fluttershy’s words sparked another adrenaline shot in Twilight, as she continues to lap her tongue inside Twilight's vaginal cavity, sending surges of pleasure throughout. The good feeling is ended abruptly when the tarantula hawk's stinger penetrates through Twilight's hind orbs.

"AHH AHHHHHH!"

The pain is incredible. The entire length of it continues to drill inside until her skin reached up to the tip of its abdomen. After pumping its potent venom, the wasp dislodges from Twilight's ass and flies toward's Fluttershy.

“Good girl! Now, the rest of you, I think it’s unfair that Twilight is getting all the fun. I want some, too.

All the flying insects that were used before gather together and, one by one, dive towards Fluttershy’s rear to make their painful deliveries. The pain makes her cringe and moan at the same time. She didn't say it, but the intensity of the stings was greater than Twilight's.

She didn't need the potion to pleasure herself from it. Her hoof rubbed her own clit, while licking Twilight's.

"Fluttershy! Are you ok?"

"I LIVE for this. Pain makes the pleasure all the more satisfying, wouldn't you agree?"

"I..."

Shhhh, it's time for the finale..."

As soon as all the insects dislodged themselves from Fluttershy’s ass, she placed her hoof in the grass to pick up her secret weapon, the bullet ant. Fluttershy held it in its hoof, looking at it with anticipation.

"This is the big one, Twilight, the bullet ant. The worst sting that I'm sure you will ever feel. But first, I need to see if he will satisfy my own needs..."

She places the ant on her backside. However, it doesn't settle on her cheek. Instead, it marches to outside of her vulva. Fluttershy moves her hoof from her private area and spreads her cheek wider to give it more room.

"I'm close. Do it. Do it NOW!"

The ant obliges, striking Fluttershy where it hurts the most. The venom from the sting is brings about a terrible aching sensation, like the feeling of a sword driven down her marehood and inside her uterus. Fluttershy lets out a pained scream that echoes throughout the area. The ant moves away just in time as a flood of liquid spills out. Her knees weaken as she goes through a series of orgasms. Struggling to catch her breath, Fluttershy stares into Twilight's eyes.

"Ooooh, oh that.... That was murderous. There is SO much pain in such a tiny little insect. Now... Now it is your turn...." Fluttershy says while catching her breath.

She moves the ant to Twilight's rump.

"I'm busy with this hole. Maybe you can sting the other."

"WAIT, Fluttershy, this might be too much for me!" shouts Twilight.

"I anticipate for it to overwhelm you."

The ant settles on Twilight's puckered anus. It twitches upon the ant's touch.

"Now, feel the burning wrath of nature!" shouts Fluttershy.

The ant burrows its stinger deep into the rim of the ring around the anus. The venom courses through and sends shockwaves of agony into her insides.

Twilight screams a scream of both incredible pain and immeasurable pleasure. Before the pain overwhelmed her senses, the potion's effect sent waves of ecstasy back her hindquarters. Her canal walls contract and loosen furiously as streams of mare cum splashes onto Fluttershy's face.

Fluttershy laps her tongue around her lips, tasting what Twilight delivered unto her. She set the ant down gently from Twilight's rump, as

Twilight collapses unto the grass, breathing heavily.

"Are you alright?" asks Fluttershy, concerned that she may have gone overboard.

"T-That's gonna hurt in the morning... Ha..." pants Twilight.

"Haha. So what score do you give that?"

"Ha...I think... I give you... a 5 out of 5...."

Twilight leans in to kiss Fluttershy. As she sensually returns a kiss right back, Twilight could have sworn that the insects started applauding. Maybe it was just her...

“Fluttershy?”

“Yes, Twilight.”

“Let’s keep this research between us, ok?”

"I promise. Thank you, Twilight.”
